Geophysical report
Any mentioned solar flare in this report has a scaling factor applied by the Space Weather Prediction Center (SWPC). Because of the SWPC scaling factor, solar flares are reported as 42% smaller than for the science quality data. The scaling factor has been removed from our archived solar flare data to reflect the true physical units.

None
C. Geomagnetic Activity Summary
The geomagnetic field was at quiet
to active levels. Coronal hole high speed stream effects subsided
near mid-period. The greater than 2 MeV electron flux at
geosynchronous orbit exceeded event threshold at 14/1130 UTC and
remains at high levels.
